Also available within the rich text editor is the ability to subscript and superscript your text by using the X2 and X2 buttons respectively. Next to the subscript and superscript options, you will notice a Ω symbol which can be used to insert commonly used characters like copyright, trademark and registered trademark symbols, to name a few. There is even a source button which can be used to place HTML directly into your rich text editor! This can be used to make specific changes to the HTML and/or utilized to simply add your youtube embed code to your page.
Did you make a mistake? No worries! You can utilize the undo and redo buttons to go back a step or to re-apply to your text. Did you copy text from an external page but did not want to copy the style? Simply click the eraser button to remove the HTML formatting from the text being used!
